To all whom it may concern:

Be it known that I, WILLIAM S. HAsLEU, a citizen oi the United States, residing at Kiester, in the county of Faribault and State of Minnesota, have invented new and useful Improvements in Corn-Planters, of which" the following is a specification.

This invention is an improved check row corn planter adapted for operation Without the use of a check Wire or line, such as is commonly em loyed, and the said invention consists in t e construction, combination and arrangement of devices hereinafter de scribed and claimed.

One objedt of my invention is to provide improved means for marking the hills as the same are planted.

A further objectis to provide improved means for operating corn-dropping devices.

a A further object is'to provide improved means for preliminarily setting or adjusting the corn-dropping operating means.

In the accompanying draWings,-Figure 1 'is'a longitudinal sectional view of a check row corn planter constructed in accordance Withmy invention. l is a detail sectional view of means for setting the cam which actuates the seed dropping and marking mechanism. F ig. isa top plan, view of the same. Fig.- 3 is a detail sectional View.

fIZwill first describe-the front truck or runner. frame 1 of'my improved. check row corn lanter. The same has an upper frame whic comprises a 'front cross bar 2, a rear crossbar 3, and side bars/1 which connect them together. .From the ends of the rear oros s bar 3 depend seed spouts 5. Furrow opening runners 6 have their rear ends ao tached to the lower ends of such spouts and their -upper,.iront ends attached to the ends of the cross .bar 2. A pair of seedhoppersj are secured on the ends of the rear cross bar' 3,, and in the bottoms of the said hoppers operate seed dropping elements 8 which may be of any'su'itahle well known construction and specifically constitute no portion of my present improvements. Rods 9 extend in wardly from the said seed-dropping elomentsami pass through guides 10 on the rear cross bar 3. Onthe said rods springs 11 are provided which serve to normally close the said seed-dropping elements by moving said rods, endwise in one direction. The said rods'9 are connected by )ivots 12 to the .outer ends of links 13, t e inner ends of which are pivotal v connected to oppositely extending arms 1 of a hell crank 15 which also has an arm 16. it willbe understood that by imparting oscillating motion to the said 'oell crank, the said dropping elements through th instrummtality oi the consections l1(-ll-il'.ll)(}f()l"8 described may be operated to muse the to drop seeds from the hopper througl's the said spouts into the furrows made by the rum'iers 6-. On the said bars 4 are hear; i? for a rock shaft '18 which carries at its ends a pair of marking hoes 39 which when impressed serve to mark the earth at points opp sitqand in line with the hills in which the .eds have been dropped. 7

The rock shaft is provided with upwardly extending arms 20 to which are attached springs 21, here shown as \TfOilBil springs having their front ends attacl'ied to arms 22 which rise from the front cross her 2. Said springs serve to normally retain the marking hoes in lhc elevated position shown in Fig. l. Said rock shaft is further provided with a projection 71%, (in the said rook shaft is mounted an oscilhding arm 24 having a fork. at its up'g'ier end in which a collar 25 is mom d. The said oscillatin es a trigger which pivots thereto, as at2'7, has an arm 28 provided with a shoulder to engage the projection 23, and. also has a rearwardly extending arm 29. A stop 30, which is immovably secured on a suitable. support, is disposed in'rear of the rock shaft 38 in such position as to be engage-d by the arm 2.) of the trigger when the oscillating arm at the rearward limit of its stroke, to disengage said triggr-Pl from the projection 23 and hence permit the springs 21 by part :6 revolving; the rock shaft to return the marking hoes to their initial elevated position. shown in F 1g. 1, it being understood that the rearward movement of the oscillating arm 24,.by the engagement of its trig er with the )rojection of the rock shait, turns the latter to the position required to cause the marking hoes wh moved dmvnwardly so as lo mark the o n hills.

The rear truck or wheel ..r :1 coin-- prisos a frame 322,. the front end of side bars are pivotnlly emmected to the r. end of the front truck frame for movcmer in a vertical plane, as at 312. A; driving shaft or axle 34 is jonrnalcd in bearings 35 with which said frame 32 is prm-idcd, and on the ends of the said driving shaft are traction and covering of a yoke 60, which yoke en ages the Wheels 36, one of which is loose on such shaft, the other s ervin to cause such shaft to be revolved when t e machine is in motion. On the said shaft is a longitudinally movable sleeve 37 which is provided with annular circumferential grooves 38, 39 at its ends. Said groove 38 is on aged by studs 40 of a fork 41 with which a be i crank 42 is pro vided, said bell crank being pivotally mountas at 43, on an arm 44 which extends inwardly from one side of the frame 32. A rock shaft 45 is j ournaled in bearings 46 on a cross bar 47 of the frame 32 and is provided at one end with a crank arm 48 to which is attached a link 49, the rear end of said link being pivotally connected to the bell crank 42. At the o posite end of said rock shaft is an arm 50 1aving a foot piece 51 which me be operated bythe driver to cause the roc shaft 45' to turn in one direction and hence cause the bell crank 42 connected to such rock shaft to move the sleeve 37 in one direction on the shaft 34'against the tension of a spring 52-, which is here shown as a coiled spring an dis osed on the shaft 34 and bearing between t e outer end of said sleeve and one of the bearings 35,

A cam 53 is loosely mounted on the shaft 34 and is provided'with oppositely extending arms 54, each presenting an eccentric cam surface 55 and a shoulder 56. Thesaid cam is provided on one side with a concentrically dispose series of ratchet teeth 57. A cross bar 58 i secured on the shaft 34 for revolu tion, and its arms are provided with open ings which form guides for parallel arms 59 cove 39 of the sleeve 37 and t ereby e sets a swivel connection with such sleeve. The outer ends of the arms 59 are sha ed to engage the ratchet teeth 57 whic form a ratchet gear on one side of the cam 53 to lock the. said yoke to the said cam, and since i the said yoke is locked to the shaft 34 by the enga emcnt of its arms with the crossbar hereby also locking the said cam to the said shaft, said yoke wlth its sleeve and the cross bar 58 coacting with the ratchet gear 57 to form a clutch for lockin the cam 53 to 50 the shaft 34 and releasing t e same therefrom, the spring 52, which moves the sleeve 37 in one direction, serving to normally keep the said cam locked or clutched to the said shaft.

A set go ar 6 1 which is provided withperipheral ratchet teeth 62, is loose on the'shaft 34 and is secured to the cam 53 for rotation therewith, as at 63. A rock arm 64 is mounted for oscillation on the shaft 34 and is provided with a gravity-acting dog or pawl 65 for engagement with the upper slde oft-he set gear. A rock shaft 66 is mounted in a bearing 67 on the cross bar 47 and has a foot lever 68, whereby it may be turned in one direction, a spring 69 being provided to turn such lever in the reverse direction. A link 70 connehts the said lever 68 to the rock arm 64 and hence enables the latter to be operated by the foot lever 68 to cause the said Wheel 61 to be turned by a.stepby-step motion and hence cause the cam 53 to be revolved with such set wheel to initially dis pose the cam ,wheel in the re uired position.-

' A rock shaft 71 is mounter in bearings 72 rovided at its ends with rock arms 73, 74, t e former provided with a tappet roller 75 which engages the cam '53. spring 76 is connected, as by rock shaft 71 and is also connected, as at 78, to the arm 32 and serves to normally draw rearwardly on the rock arm 74 and hence normally move the rear end of the rock arm' 73 downwardl The said rock arm '74 is connected to t e arm 16- of the bell crank lfi as'by means ofa rod 79 and is also connected means of a rod Z7 ,to the rock arm 74 of the ,to the collar25 by a rod 80, whereby motion may be imparted from the rock shaft 71 which is oscillated by the cam 53, to the said dropping mechanism and to the rock shaft 18 w ich serves to actuate the marking hoes.

In order to throw the seed-dropping mcc'h- Y anism and the marking mechanlsm out of operation it is only necessary to unclutch the cam53 from the shaft 34, which may be done by actuating the foot lever 51 to cause such lever, throughv the instrumentality of the connecting devices"hereinbefore described, to move. the yoke 60 which -constitutes a clutch element out of engagement with the gear 57, which constitutes the other clutch element. To initially set such cam before starting the machine at the beginning of a row, it is onl necessary for thedriver by means of the cot lever 68 and the connections hereinbefore described to partially turn such cam so that the same wlll cause the seed-dropping mechanism to be so actuated as to deposit the seed in line with those of the previously lanted hills.

Having thus describe the invention, what is claimed as new, is

1. In a check row planter, the combination of a rocking marker shaft having a pro.

to cause the spring to impart a marking stroke to the marker.

2.- In a check row planter having a front truck or runner frameand a rear truck or wheel frame flexibly connected to'such front truck, a seed dro ping mechanism on such front truck, a roc mg marker shaft also on such front truck having a projection, springs vated position, a rock arm, means to actuate the same, a trigger having a shoulder to engage the projection of the marker shaft and a to normally support the markers in an ele- &

move the latter and such rock arm in one direction against the tension of the springs, means to trip such trigger and release the same from the said projection to cause the springs to impart a marking stroke to the markers, an operating lever on the rear truck to which such seed dropping mechanism and such rock arm are connected, and means carried by such rear truck to operate such operating lever.

3. In a check row planter having a front truck or runner frame and a rear truck or wheel frame flexibly connected to such front truck, a seed dro ping mechanism on such front truck, a roe mg marker shaft also on such front truck having a projection, springs to normally support the markers in an elevated position, a rock arm, means to actuate the same, a trigger having a shoulder to en gage the projection of the marker shaft and i move the latter and such rock arm in one direction against the tension of the sprin s, means to trip such trigger and release t e same from the said projection to cause the springs to impart a marking stroke to the markers, an operating lever on the rear truck to which such seed dropping mechanism and such rock arm are connected, a driving shaft for the rear truck, a cam loose thereon and engaged by such operating lever to actuate the planting and marking mechanisms, said cam having a ratchet gear, a spring coacting with said cam to o erate said. operating lever, a clutch for sai cam to lock the same to said shaft, an arm loose on said shaft and having a spring pressed. pawl engaging the ratchet gear and. a lever connected to said arm to operate the same for setting the cam.
